So i hook up my old mercury tibook and it will run with battery inserted (yes battery holds a charge), and the plug in. If i unplug it, it shuts off, and the time is random with the date set sometime in 1969. Tried resetting the pram by pushing that little button on the back and tried resetting the pmu. Anyone have any ideas? Do I need to put in a new pmu? -- Your friends confine you in their worlds, one by one, a string of pearls.
